(Main)Thermal insulation products for buildings - In-situ thermal insulation formed from exfoliated vermiculite (EV) products - Part 2: Specification for the installed products
General Information
- Abstract
This European Standard specifies the requirements for the four types of exfoliated vermiculite products Vermiculite Aggregate (EVA), Coated Vermiculite (EVC), Hydrophobic Vermiculite (EVH) and Premixed Vermiculite (EVM), containing less than 1 % organic material as defined by Annex D of EN14317-1:2004 for in-situ insulation of roofs, ceilings, walls and floors.
This Part 2 of the standard is a specification for the installed products.
This Part 2 of this standard also specifies the checks and test procedures to be used for the declaration made by the installer of the product.
This European Standard does not specify the required level of all properties to be achieved by a product to demonstrate fitness for purpose in a particular application. The required levels are to be found in regulations or non-conflicting standards.
This European Standard does not include factory made insulation products of formed shapes and boards made with exfoliated vermiculite or in-situ products intended to be used for the insulation of building equipment and industrial installations.
This European Standard does not specify performance requirements for airborne sound insulation and for acoustic absorption applications.

Overview
EN 14317-2:2007 is the CEN specification for in‑situ thermal insulation formed from exfoliated vermiculite (EV) products once installed. It covers four product types - Vermiculite Aggregate (EVA), Coated Vermiculite (EVC), Hydrophobic Vermiculite (EVH) and Premixed Vermiculite (EVM) - containing less than 1% organic material (per EN 14317-1). Part 2 is a non‑harmonised, installer‑focused document that defines requirements, measurement procedures and the installer’s declaration for roof, ceiling, wall and floor applications. It excludes factory‑made boards, insulation for building equipment/industrial installations and acoustic performance requirements.
Key topics and technical requirements
- Compliance link: Installers must use products that comply with EN 14317-1 and follow manufacturer guidance and national regulations.
- Thermal calculations: Required thickness (dr) is determined from the specified thermal resistance (Rs) and the declared thermal conductivity (λD) using the relationship:
dr = Rs × λD.
Declared thermal resistance (RD) is calculated as RD = di / λD, where di is installed thickness. - Installed thickness rules: The mean installed thickness must be at least the required thickness; no single measurement may be less than 80% of the specified value.
- In‑situ measurements: Installers must verify thickness and cavity fill. Minimum of five thickness measurements per 100 m² is required. In dispute cases, EN 823 pin‑and‑plate method applies.
- Installer’s declaration: Must record trade name/code, declared thermal resistance, required and installed thickness, volume used, installation date and a statement that installation followed the specified procedure.
- Building suitability: Annex A provides guidance on substrate condition, ventilation, vapour barriers and retention of loose-fill products.
Practical applications and users
This standard is intended for practical use by:
- Installers and contractors applying in‑situ exfoliated vermiculite insulation
- Specifiers, architects and engineers who set required thermal resistance and cavity dimensions
- Building inspectors and compliance officers verifying installation records and declarations
- Manufacturers and suppliers ensuring product labelling aligns with EN 14317-1
Use cases include insulating lofts, pitched/flat roofs, floor voids and cavity walls where loose‑fill or bonded vermiculite products are appropriate.
